Five pectoral appendages, one of which reaches beyond the tip of 

 the ventral ; lobes of the caudal not produced into filaments ; the 

 distance between the root of the ventral and anal fins much less than 

 the length of the head. No distinct spine above the angle of the 

 prteoperculum. Back with eight distinct brown longitudinal lines, 

 and about as many below the lateral line.

Description. — Tins species is moderately elongate, its greatest 

 height, below the origin of the soft dorsal, being 44- ia the total 

 length. The taU is compressed and rather elevated, its height, 

 below the end of the dorsal, being one-seventh of the total length. 

 The length of the head is -11 in the total; its width between the 

 eyes is 3^ in its length. The snout is rather short and obtuse, half 

 as long as the diameter of the eye, which is nearly one-fourth of the 

 length of the head. The cleft of the mouth is wide, the upper 

 maxillary reaching to the middle of the distance between the orbit 

 and the posterior margin of the pra?opercidum, and its length being 

 2-J- in the length of the head. The posterior margin of the pra^oper- 

 culum descends obliquely backwards in a slight cui've ; it is serrated, 

 the dcnticulations becoming coarser inferiorly ; the angle forms a 

 membranaceous lobe, rounded and produced. 



The origin of the first dorsal is in the vertical from the eighth 

 scale of the lateral line, or from tlie middle of the interspace betMeeu 

 the root of the pectoral and ventral fins. The first spine is minute ; 

 the second is the strongest, all the others being flexible ; the tlni-d 

 is the longest, and Ig in the length of the head ; the fom-th is longer 

 than the second, and the following rnpidly decrease in length. A
